Seagate 3TB st3000dm001 Mac OS problem.

Hello,

Recently, i bought a brand new seagate barracuda 3TB hard drive (ST3000DM001). When i plugged it via usb in my macbook pro early 2010 mode (latest lion os), the driver wasn't even visible. Disk utility couldn't read it too. So, i used 3 different types of external cases (all of them support mac OS and hard drives bigger than 2TB) but nothing changed. After that, i did the same thing with my old mac mini (OS 10.6.8), but once again, nothing happend. The only way to see the hard disk is with windows 7, by using bootcamp on my macbook pro.Is there anyone out there who knows anything about this problem or how to solve it ? Thank you for your answers!

Mac OS X (10.7.5)

Does the Seagate show up in Disk Utility in any of the external cases? If it does, you can format it there.

Otherwise, if it's accessable in BootCamp, try using Win 7 to format it in exFAT. Mac OS X can see that.

No, it does not! 😟

I already tried this. Even after i formatted the disk in exFAT, it wasn't readable by disk utility.

I have the same issue ..

I have a Mid 2010 MacbookPro .... using Sharkoon drivelink usb2.0 (it apparently supports 4T.. works fine for 2T) ..and the external drive is simply not recognised .... no logging ... nothing ...

Can someone from apple support pls advise??? Is there some diagnostics we can run or another solution?
